GENERAL WARNINGS FOR ANY INTERVENTION CARRIED OUT ON THE CHAIR:
Before any repairs and/or modifications on the chair, analyse the intervention points so
that you can put the chair back together again.
When dismantling one or more components, always be careful of the weight and/or the
weight of the component(s) which it supports and/or holds.
Before any mechanical intervention on the chair, remove the fuse from the chair (see
section «Fuse»).
Put some medium threadlock on the screws which are not locked with a brake nut and/or
which are not adjustment screws.
